Detention Ponds

Detention ponds used for storm water management provide temporary storage of rainwater runoff. Where the capacity of a downstream pipe or stream is less than the runoff flows from development, a detention pond temporarily stores water so it can be released slower for a longer amount of time.

Detention ponds come in different shapes and sizes and can be wet or dry. Due to the land requirements for a pond, many commercial developments choose to locate detention below ground, enabling the dual use of the same area for both surface access and drainage. These are known as detention tanks. Detention ponds can be one component of the sustainable drainage features of a development project or of a community.

A visit to any detention pond will provide an opportunity to see the variety of wildlife that populates the area. Wet ponds and wetlands located in Surrey are safe because birds and frogs naturally control insects along with the City’s pest management system.
